PORTABLE TURN-TABLE.

Patented April 24, 1906.

Application tiled November 6. 1905. Serial No. 286.018.

To (1./ mhd/'rb it NMa/gj calcule/711; Be it known that' 1, CHARLES W.HILLEN- BRAND, a citizen of the United States, residing at Kansas City,in the county of Vyandotte a1id.;State of'Kansas, have invented certainAnew and useful Iinprovenientsin Portable Turn-Tables, of which thefollowing is a specification.

My invention relates to improvements in portable turn .ftables; and myobject is' to provide an appliance whereby the handling of motor-cars orother vehicles in garages and manufactories will be greatly facilitated.

' The turn-.table being portable may benioved around vat will and, as itis selfscontained,

said floor. It enables the car to turn within its length, and therebyreduces the space ordinarily required for maneuvering cars. Thus thecapacity of the garage is increased. It also peunits th` ear to face thedoor, so that the risk and inconvenience arising from backing out of thegarage is obviated.

Inv order that the invention Ymay be fully understood, reference willnow be made to the accompanying drawings, in which- Figure 1 representsa plan view of my iinproved turn-table. Fig. 2 is an irregular longitudinal section of same, taken on line H Il of Fig. 1. Fig. 3 is av.central transverse section taken on line IH III ofFig. 1,.' 4 is anenlarged side elevation of a` two'- wheel truck, across -section of asupporting arm mounted upon said truck, and an annular track upon whichthe truck is mounted, allof which form part of theinvention. Fig. 5 is avertical section of same, taken on line V V of Fig. 4. Fig. 6 is atransverse section taken on line VI Vl of. Fig. 1, showing one of thetransporting j wheels employed in carrying out the invention" in 'anelevated position.

Fig. 7 is a transversesection taken on the same plane as Fig; l6,showing the transporting-wheel in its loweredi'iosition.v Fig. 8 is aplan view of saine, partly in section. Fig. 9

- is a longitudinaljsecti'on ofoneof the .transporting-wheels and aArectangular frame in which it is mounted, taken'on'line 1X IX of Fig. 7.Fig. 10 is a vertical longitudinal 'sec- .tion taken on line X X'of Fig.6, showing part of the mechanism for raisingand lowering thetrarisporting-wheels. Fig.Y 11 1s an enlarged vertical section taken online XI I of Fig. 1. Fig. 12 isv a transverse section taken on lineXlIXH of Fig. 1-1. Fig. 13 is a broken plan view of a shalt and a castingfixed thereon, both of which are employed in assisting to raise andlower adjustable ap'- proaches forming part of the invention. Fig. 14 isa seqtion taken on line XIV'XIV of 1. Fig. 15 is an enlarged broken sideelevation. of a runway, an adjustable approach pivoted thereto, a leverand counteriight for holding said approach in either its raised orlowered position, and one of a plurality of slices for supporting theend of the runwa when the latter is in its lowered position, all ofwhich form part of the invention.

ln carrying out the invention l employ a centrally-disposed track 1,preferably annular in plan view to save weight and material, upon whichis mounted a plurality of twowheel trucks 2, each of which comprises aframe 3, provided at their opposite ends with axles 4, journaled in theends of said frame, and a pair of wheels 5, fixed upon said axles, theperipheries of said wheels being slightly conical to properly travelupon track 1.

Frames 3 are provided with centrally-dis posed transverse bearings 6 forthe reception of sockets 7,1ooselyitting over said bearings, so thatthewheels of the trucks may readily accommodate themselves to any slightirregularities which may exist in the surface of track 1 and so the loadwill be equally distributed upon each of said wheels. Sockets 7 areformed in the under sides of a pair of diagonally arranged supportingarms S, crossing each other at their central portions, which areprovided with hubs 9, one of which rests upon the other, as shown inFig. 3. The lowermost hub rests upon a hub 10, connected to track 1 byradial arms 11. Hubs 9 are held in vertical alinenient by means of abushing 12, resting upon the upper surface of hub 10 and held invertical alinementl with the latter by means of a king-bolt 13,extending upwardly through hub 10 and the bushing and provided at its uper threaded end witli a washer 14 and a cfimping nut 15. In order toprevent the washer from being forced into frictional contact with theupper hub 9 by means of the clamping-nut, l extend the bushing slivhtlyabove said hub,'as shown in Fi 3.

Said means consist of lugs Tl, projecting laterally fromplates '67 into recesses 72 in flanges G9 to swing independently ofcastings 62 until the lugs 71 Contact with the shoulders forming theends ot' the recesses, when, of course, they swing together theremainder ol" the distance and carry the approaches therewith.

73 designates av plurality of shoes, one pair of which is arrangedbeneath each-end ot' the runways. Each shoe is provided with a pair ofupwardly-extending cars 74, embracing the opposite sides of lugs 75,depending from the under side of sockets 57, the shoes being looselysecured to the lugs by pins 76, extending through'slots 77 in the ears.By thus slotti ng the ears the lugs will bear upon the shoes when thelatter are resting upon the floor, and thus relieve pins 76 of allweight, said pins being provided merely for the purpose of raising theshoes from the floor with the approaches. (See dotted lines, Fig. 15.)

ln operation the approaches and the shoes are adjusted to theirlowermostpositions by throwing levers 69 outwardly (see full lines, F ig. 15) inorder that the ends of the runways may be supported by said shoes. Thetransporting-wheels are then raised from the floor by throwing levers5() to the position indicated by full lines, Fig. 6. This operationlowers track 1 to the floor, so that the entire weight of the turn-tablewill be supported by said track, trucks .2, and the shoes. The n10-tor-car or other vehicle is then run over the approaches and onto therunways. The runways, with the-vehicle, may then be turned, as upon apivot, toward any objective point after the approaches and the shoeshave been raised from the floor, so that the entire load will be carriedby trucks 2 and track 1. The transporting wheels need only be loweredwhen it is esired to move the turn-table from place to place, and whenoccupying their lowermost position the slices, approaches, and the trackwill of course be raised from the floor, as shown in Fig. 2.

The parts are detachable and interchangeable, so they may be readilyrepaired or replaced when worn out, and by making the turn-table inskeleton form, as illustrated, all neeldless weight and material aredispensed wit 1.

This permits leversl While I have described the inventioil as a portableturn-table, I do not wish to be limited to this construction, as itcould of course be readily converted into a stationary one by dispensingwith the transporting-wheels and the means for operating the latter'.The adjustable` approaches, while desirable, could also be dispensedwith by arranging the ends of the runways close enough to the Hoor topermit the vehicle to easily run upon said runways, and when so arrangedthe shoes could also be omitted.
